Copper is a soft metal material. The surface layer is red orange with metal texture at the beginning, and the hydroxide is dark purple. Because of its good plasticity, high heat transfer and conductivity, it is a common raw material in cables, household appliances and electronic components. It can also be used as building decoration materials to form many aluminum alloys. Moreover, copper corrosion resistance is very good, is a durable metal material, can be purchased several times and high quality of its physical properties. Therefore, copper bolts have inherited this characteristic very well. Compared with bolts made of stainless steel plate, iron, aluminum and other materials, large cap type lantern rivet is still loved by many medium and high-grade commodity manufacturing enterprises due to its high-quality conductivity and long-term corrosion resistance, and its main use is also very wide.

Copper bolts are generally divided into round mouth copper bolts, small flat head copper bolts, countersunk head copper bolts, half space center copper bolts, solid core copper bolts, letter nails, step copper bolts, etc. Round mouth copper bolts are mainly used for riveting places with large transverse load. Countersunk head copper bolts are usually used for riveting places with smooth surface and small load. Half space center copper bolts are generally used for non-metallic riveting places. Generally speaking, customers of semi hollow rivet manufacturers choose copper bolt because of its stronger conductivity, corrosion resistance and more high-end atmospheric appearance. Therefore, in some household appliances, power energy and chemical manufacturing industries, as well as some new industries and new technology fields, the corresponding materials are more popular!
